No mods really needed for spec1 remap, just a good engine in good working order. Good oil, good plugs, good 97+ fuel, no boost leaks or split lines (we can check these out)
If its got a blow off dump valve we will tell you to bin it and get a full recirc fitted like the Forge 007P (£85 with yellow spring)
To compliment the remap spec1 remap we suggest having the Pipercross filter and forge 007p.
Spec2 remap you need turbo back upgrade exhaust system.
What year is you car?
